FRUST-REMOVER,

specification of Iletters Patent.

rateatea Jury t, rata To all 'whom it may concem: i Be it known that we, J osEPH J. I'innu and WILLIAM NOTTBERG, citizens of the United States, residing at Kansas City, in the county'of Jackson 'and State of Missouri', have invented certain new and useful Improvements in Frost-Removers, of .which the following is a specification. I

Our invention relates to improvements in frost removers.

The object of our invention is to provide a simple and efficient mechanism for remov- `ing frost, snow or ice from. window panes,

brlnsparent automobile wind shields and the Our invention is particularly adapted for use on street or railway cars which are equipped with electrical power and air brake mechanism.

In the accom anying drawin'gs which illustrate the pre erred form of our invention, Figure 1 is" a view partly in Vertical section and partly in side elevation of the apparatus. Fig. 2 is a front view of the noz'zle.

Similar characters of reference designate similar parts in the different views. i

In the draw'ings wehave shown our ,invention applied to a car, 1 designating the car body and 2 the vestibule. Supported by the-body is an ordinary air pump such as is commonly employed in air -brake mechanisms, The pump, which is designated by 3 is connected by a vconductor 4, having a check valve 5, with a receiver 6 which is connected with a conductor 7 which includes a Chamber 8 and a flexible discharge portion 9 having a nozzle 10. In the. Chamber i ing through the nozzle 10 to that idesired;

Intermediate of the valve 12 and Chamber 8 is a branch pipe 13`to which is connected any suitable pressureQ indicating gage 14,

w the pipe 13 being connected to the conductor 7. For movably supporting thefflexible portion 9 is a cord 15 one end of which is secured to the portion 9 by a suitable clip or fastening device 16, and the other end of which supports a weight 17 pulleys 18-and 19 fastened to the under side of the roof 20.

of the vestibule being provided forsupporting the cord 15. Preferably the weight 17 is sufliciently heavy to lift the flexible portion 9. The' fiexible portion 9 is adapted to be drawn downward to a position in which the nozzle 10 will discharge heated air upon the inner side of a window pane 21 with which the front wall of the vestibule 2 is provided.

In the operation. of our invention the air passing from the pump 8 to the receiver 6 b way of the conductor 4 and past the c eck valve 5, and from the receiver to the Chamber 8 is heated in the chamber 8 and escapes from the discharge-portion 9 by way of the nozzle 10. If the nozzle is drawn downwardly to a position in which the heated air can impinge against the pane 21, any frost, snow or ice thereupon will be melted,

so as to permit the motorman to look f through the window. After the snow, ice

or frost has been cleared from the window.

1. In a frost reinover5 the combination with a car vestibule having a window pane, of a conductor having a fiexible discharge portion movable toward and from a position in which it will discharge air against said pane, means for normally moving said fiexible portion from said position, means for heating the air in said conductor, a receiver connected with said conductor, a regulating valve intermediate of the receiver and the heating'means, an air pu p, a conductor connecting the receiver an air pump, and a check valve in the`last named conductor.

2. In a frost remover, a car, a tank carried by' the Acar and adapted to contain air under pressure, a conductor connected with said tank and having a nozzle arranged to discharge air against a window pane, means pressure, a conductor'con'nected With said tank and having a nozzle arranged to discharge'air against a Window pane, means for controlling the flow of air through said conductor, and electrical means for 'heating said air.

4. In a frost remover, a car, a tank carried w fpressnre, a conductor connected Wlth said thereby and adapted to contain air under pressure, a conductor connected with said tank and having a nozzle arranged to discharge air against a Window pane, the conductor having a heating chamiber, electrical means in said Chamber for heating the same, and means for controlling the flow of air through said (conductor.

5. In a frost remover, a car, a conductor provided With a flexible portion having a nozzle, means carried by said car for supplying said conductor With air under pressure, means for heating said air, and yielding means for normally holding the nozzle in a raised position.

6. Ina frost remover, a car, a conductor having a nozzle, means carried by the car for supplying heated air under pressure to said nozzle through said conductor, and means for controlling the flow of air through Vsaid conductor. w

7. In a frost remover, a car, a conductor provided With a flexible` portion provided with a nozzle arranged to discharge air against a window pane, and means for sup- `means by' which said Weight normally lifts the nozzle to a raised position, and means for supplying heated air under pressure to said nozzle through said conductor.

9; In a frost remover, a car, a tank carried thereby and adapted to contain air under tank' and having a flexible portion provided With a nozzle, a valve for controlling the flow of air through said conductor, means for lheating the air passing through the conductor, and means carried by the car for supplying the tank with air under pressure.

10. In a frost remover, a car, a tank carried thereby and adapted to contain air under pressure, a conductor connected With said tank and having a fiexible portion providedv with a nozzle, a valve in said conductor controlling the -fioW of air therethrough, means for heating the air passing through the conductor, and yielding means for normally raising the nozzle to a raised position.
